What is the y-intercept?
Because we do not have an integer as the y-intercept all of the time, we need to know how to get the equation for a line a different way. So how do we write equations for these graphs?
POINT SLOPE FORMULA
POINT SLOPE FORMULA IS FROM THE SLOPE FORMULA!
TO USE POINT SLOPE FORMULA TO WRITE THE EQUATION FOR A LINE, ALL YOU NEED IS THE SLOPE AND ANY POINT!
USING POINT SLOPE FORM PRACTICE
